The Pippau ( Crepis ) constitute a genus within the family of Compositae (Asteraceae). The approximately 200 species are widespread in North America , Eurasia and Africa . The common name Pippau comes from the Slavic ( Polish pępawa) and was used for the related dandelion ( Taraxacum officinale ).

Appearance and leaves

The Pippau species are annual, biennial or perennial herbaceous plants that reach heights of 3 to 120 centimeters, depending on the species. They usually form tap roots , sometimes they form rhizomes . The independently upright to creeping stems are simple or branched.

The mostly stalked leaves are often arranged in basal rosettes; they can also be distributed on the stem. The petioles are more or less winged. The leaf blades are simple, lobed to pinnate. The leaf margins can be smooth, serrated or serrated.

Inflorescences and flowers

The upright cup-shaped inflorescences are sometimes single or mostly in branched, umbrella-clustered to racemose or panicle-like overall inflorescences . The involucre is cylindrical to bell-shaped. The bracts are several rows. The outer bracts overlap ± like a roof tile, they become gradually longer towards the outside and the longest are 1/4 to 2/3 longer than the innermost; the inner ones usually have the same length. The inner bracts are linear-lanceolate, hairy on the outside with simple or glandular trichomes or rarely glabrous and inside glabrous and adjoining silky hair. The flat or convex flower head base rarely has chaff leaves or bristles.

The flower heads contain only five to over a hundred ray florets . The color of the ray florets is usually yellow or orange, sometimes white, pink or reddish to rarely purple.

fruit

The yellow, brown, green, red or black achenes are finely prickly or smooth. cylindrical to spindle-shaped achenes have ten to twenty ribs and a narrowing, pointed or beaked upper end. The durable or early falling pappus consists of 80 to 150 white to light yellowish, flexible, feathery bristle hairs that are more or less the same or the outer ones are shorter; they can stand in one or two rows.

Sets of chromosomes

The basic chromosome numbers are x = 8, 7, 6, 5, 4 or 3. There are the ploidy degrees diploidy , tetraploidy, hexaploidy and octoploidy.

Taxonomy

The genus Crepis was established by Carl von Linné in 1753 . The generic name Crepis means shoe sole and refers to the shape of the leaves. Type species is Crepis biennis L.

Steud. , Anisoderis Cass. , Anisoramphus DC. , Anthochytrum Rchb. , Anthochytrum Rchb. f. , Aracium Neck. , Barkhausia Moench , Barckhausia DC. , Berinia Brign. , Billotia Sch.Bip. , Brachyderea Cass. , Calliopea D.Don , Catonia Moench , Ceramiocephalum Sch.Bip. , Choeroseris Link , Closirospermum Neck. , Crenamum Adans. , Crepidium Exchange , Crepinia Rchb. , Cymboseris Boiss. , Derouetia Boiss. & Balansa , Dianthoseris Sch.Bip. , Dianthoseris Sch.Bip. ex A.Rich. , Dysodea Borkh. , Endoptera DC. , Gatyona Cass. , Geblera Andrz. ex Besser , Geracium Mössler , Geracium Rchb. , Hapalostephium D.Don , hieracioides Fabr. , Hostia Moench , Idianthes Desv. , Intybellia Cass. , Intybellia Monnier , Lagoseris M.Bieb. , Lepicaune Lapeyr. , Limnocrepis fourr . , Limnoseris Peterm. , Melitella Sommier , Myoseris Link , Nannoseris Hedberg , Nemauchenes Cass. , Omalocline Cass. , Pachylepis Less. , Paleya Cass. , Phaecasium Cass. , Phalacroderis DC. , Psammoseris Boiss. & Reut. , Psilochenia Nutt. , Pterotheca Cass. , Rhynchopappus Dulac , Rodigia Spreng. , Sclerolepis Monnier , Sclerophyllum Gaudin , Soyeria Monnier , Succisocrepis Fourr. , Trichocrepis Vis. , Wibelia G.Gaertn., B.Mey. & Scherb. , Zacintha Mill.

External system

The genus Crepis belongs to the subtribe Crepidinae from tribe Cichorieae in the subfamily Cichorioideae within the family Asteraceae . Without the species of the genera Lapsana and Rhagadiolus , the genus Crepis is paraphyletic. This is still being discussed controversially. The list of species below corresponds to this extent of the paraphyletic genus Crepis according to Enke & Gemeinholzer 2008.

Species and their distribution

The genus Crepis is widespread in the northern hemisphere in North America , Eurasia and Africa .
